Technical Field
[0001] The present invention relates to a compound or a pharmacologically acceptable salt
thereof that has an excellent antagonistic effect on a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor and is useful as a therapeutic agent for bronchial asthma, chronic obstructive
pulmonary disease, or the like.
Background Art
[0002] In bronchial asthma or chronic obstructive pulmonary disease (COPD), bronchoconstriction,
airway inflammation, mucus secretion, coughing, and the like increase. Substance P
or neurokinin A is associated with an airway contracting effect, an inflammatory effect,
coughing, and mucus secretion. A compound that antagonizes receptors of both substance
P and neurokinin A (a neurokinin NK
1 receptor and a neurokinin NK
2 receptor) may suppress the above-mentioned physiological effects (Non-Patent Documents
1 and 2). Although nonpeptidic low-molecular weight compounds that antagonize both
the neurokinin NK
1 receptor and the neurokinin NK
2 receptor have been disclosed (Patent Documents 1 and 2), the use of the compounds
as pharmaceuticals has not been approved. Meanwhile, acetylcholine exhibits a potent
airway contracting effect by acting on a muscarinic M
3 receptor (Non-Patent Document 3). Compounds that antagonize the muscarinic M
3 receptor have a bronchodilating effect (Patent Documents 3, 4, and 5) and are used
as bronchodilating agents (Non-Patent Document 4). It has been described that a bronchodilating
effect which is more potent than the bronchodilating effect exhibited by antagonizing
each of the receptors individually is exhibited by antagonizing both the muscarinic
M
3 receptor and the neurokinin receptors (Patent Document 6). However, since no compound
that antagonizes the neurokinin NK
1 receptor and the neurokinin NK
2 receptor has been marketed as a therapeutic agent for bronchial asthma or COPD, single
agents cannot be used in combination. There has been demand for a single compound
which has potent bronchodilating, anti-inflammatory, antiussive, and expectorant effects
by antagonizing all of the neurokinin NK
1 receptor, the neurokinin NK
2 receptor, and the muscarinic M
3 receptor.

Disclosure of the Invention
Problems to be Solved by the Invention
[0005] The inventors of the present invention assiduously studied the synthesis of a single
compound that has an antagonistic effect on all of the neurokinin NK
1 receptor, the neurokinin NK
2 receptor, and the muscarine M
3 receptor as well as a pharmacological activity over a long period. As a result, they
found compounds that solely exhibited an antagonistic effect on all the receptors
and showed drug efficacy in a sustained manner. Thus, the present invention was accomplished.

[0058] A "compound having an antagonistic effect on a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor" is a compound having all of a neurokinin NK
1 receptor antagonistic effect, a neurokinin NK
2 receptor antagonistic effect, and a muscarine M
3 receptor antagonistic effect.
[0059] The expression "having a neurokinin NK
1 receptor antagonistic effect" means to have an ability to bind specifically to a
crude membrane sample of neurokinin NK
1 receptor-expressing cells and have a neurokinin NK
1 receptor antagonistic effect evaluated by inhibiting or suppressing an action of
a neurokinin NK
1 receptor agonist, such as substance P-induced airway contraction. Whether a specific
compound has such an antagonistic effect can be easily determined by those skilled
in the art according to the following method, for example.
[0060] Examples of such a method include a method in which the ability to bind to a neurokinin
NK
1 receptor is measured according to the measurement method (2.3 Receptor binding assay)
described in the literature (
European Journal of Pharmacology, 2008, vol.586, 306-312) and airway contraction is measured according to the literature (a modified method
of the methods described in
British Journal of Pharmacology and Chemotherapy, 1962, vol.19, 168-182 and
European Journal of Pharmacology, 1992, vol.231, 31-38). When the ability to bind to a neurokinin NK
1 receptor is a predetermined constant value (Ki = 1 µM, preferably Ki = 10 nM) or
lower and the dose intratracheally administered for the suppression effect is a predetermined
constant value (ID
50 = 1 mg/kg, preferably ID
50 = 50 µg/kg) or lower, an antagonistic effect is determined.
[0061] The receptor of substance P is a neurokinin NK
1 receptor.
[0062] The expression "having a neurokinin NK
2 receptor antagonistic effect" means to have an ability to bind specifically to a
crude membrane sample of neurokinin NK
1 receptor-expressing cells and have a neurokinin NK
2 receptor antagonistic effect evaluated by inhibiting or suppressing an action of
a neurokinin NK
2 receptor agonist, such as neurokinin A-induced airway contraction. Whether a specific
compound has such an antagonistic effect can be easily determined by those skilled
in the art according to the following method, for example.
[0063] Examples of such a method include a method in which the ability to bind to a neurokinin
NK
2 receptor is measured according to the measurement method (2.3 Receptor binding assay)
described in the literature (
European Journal of Pharmacology, 2008, vol.586, 306-312) and airway contraction is measured according to the measurement method (2.6 Bronchoconstriction
in guinea pigs). When the ability to bind to a neurokinin NK
2 receptor is a predetermined constant value (Ki = 1 µM, preferably Ki = 10 nM) or
lower and the dose intratracheally administered for the suppression effect is a predetermined
constant value (ID
50 = 1 mg/kg, preferably ID

[0064] The expression "having a muscarine M
3 receptor antagonistic effect" means to have an ability to bind specifically to a
crude membrane sample of muscarine M
3 receptor-expressing cells and have a muscarine M
3 receptor antagonistic effect evaluated by inhibiting or suppressing an action of
a muscarine M
3 receptor agonist, such as acetylcholine-induced airway contraction. Whether a specific
compound has such an antagonistic effect can be easily determined by those skilled
in the art according to the following method, for example.
[0065] Examples of such a method include a method in which the ability to bind to a muscarine
M
3 receptor is measured according to the measurement method (Human muscarinic receptor
studies) described in the literature (
Life Sciences, 1993, vol.52, 537-544) and airway contraction is measured according to the measurement method (a modified
method of the method described in Bronchospasmolysis in anaesthetized dogs). When
the ability to bind to a muscarine M
3 receptor is a predetermined constant value (Ki = 1 µM, preferably Ki = 10 nM) or
lower and the dose intratracheally administered for the suppression effect is a predetermined
constant value (ID
50 = 1 mg/kg, preferably ID
50 = 50 µg/kg) or lower, an antagonistic effect is determined.
[0066] Such a method for identifying a "compound having an antagonistic effect on a neurokinin
NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor" also falls within the scope of the present invention. This method comprises
(i) a step of determining whether a test compound has a neurokinin NK
1 receptor antagonistic effect; (ii) a step of determining whether the test compound
has a neurokinin NK
2 receptor antagonistic effect; and (iii) a step of determining whether the test compound
has a muscarine M
3 receptor antagonistic effect. In this method, the steps (i) to (iii) can be performed
in any order, or two or more steps can be performed in parallel. A test compound that
is determined to have a receptor antagonistic effect in all the steps (i) to (iii)
is identified as a "compound having an antagonistic effect on a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor."
[0067] The step (i) comprises (a) a step of measuring an ability of a test compound to bind
to a neurokinin NK
1 receptor and (b) a step of determining whether the test compound inhibits or suppresses
an action of a neurokinin NK
1 receptor agonist. Examples of the neurokinin NK
1 receptor agonist include substance P. Examples of the action of a neurokinin NK
1 receptor agonist include substance P-induced airway contraction.
[0068] The step (ii) comprises (c) a step of measuring an ability of a test compound to
bind to a neurokinin NK
2 receptor and (d) a step of determining whether the test compound inhibits or suppresses
an action of a neurokinin NK
2 receptor agonist. Examples of the neurokinin NK
2 receptor agonist include neurokinin A. Examples of the action of a neurokinin NK
2 receptor agonist include neurokinin A-induced airway contraction.
[0069] The step (iii) comprises (e) a step of measuring an ability of a test compound to
bind to a muscarine M
3 receptor and (f) a step of determining whether the test compound inhibits or suppresses
an action of a muscarine M
3 receptor agonist. Examples of the muscarine M
3 receptor agonist include acetylcholine and methacholine. Examples of the action of
a muscarine M
3 receptor agonist include acetylcholine-induced airway contraction.

is expressed, intact cells, or the like and a labeled substance bonded to each receptor
can be used.
[0071] Furthermore, a compound identified as a "compound having an antagonistic effect on
a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor" in the method of the present invention is useful as a medicament and particularly
useful as an agent for preventing or treating bronchial asthma, bronchitis, chronic
obstructive pulmonary disease, coughing, sputum oversecretion, rhinitis, pain, anxiety,
depression, convulsion, Parkinson's disease, incontinence of urine, irritable bowel
syndrome, prostate hypertrophy, vomiting, peptic ulcer, retina testing, acute iritis,
keratitis, miosis, saliva oversecretion caused by an anesthetic, airway secretion,
and/or ulcer. Therefore, a method of the present invention for identifying the "compound
having an antagonistic effect on a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor" is also included in the present invention as a method for identifying an
agent for preventing or treating such diseases.
Advantageous effects of Invention
[0074] The compound of the present invention or a pharmacologically acceptable salt thereof
represented by the general formula (I) is useful as a medicament because the compound
exhibits an antagonistic effect on a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor and particularly useful as an agent for preventing or treating bronchial
asthma, bronchitis, chronic obstructive pulmonary disease, coughing, sputum oversecretion,
rhinitis, pain, anxiety, depression, convulsion, Parkinson's disease, incontinence
of urine, irritable bowel syndrome, prostate hypertrophy, vomiting, peptic ulcer,
retina testing, acute iritis, keratitis, miosis, saliva oversecretion caused by an
anesthetic, airway secretion, and/or ulcer.
[0075] The three most common complaints of chronic obstructive pulmonary disease (COPD)
are breathlessness, chronic coughing, and chronic sputum secretion. The underlying
cause of the disease is inflammation of the airway. Neurokinin A and substance P are
reported to be associated with coughing and sputum as well as inflammation in COPD.
Acetylcholine is associated with breathlessness. The compound of the present invention
or a pharmacologically acceptable salt thereof represented by the general formula
(I) suppresses all the major symptoms of COPD by antagonizing a neurokinin NK
1 receptor, a neurokinin NK
2 receptor, and a muscarine M
3 receptor simultaneously, and can also contribute to suppression of progression of
pathological conditions by resolving inflammation, which is an underlying cause.
[0076] The compound of the present invention or a pharmacologically acceptable salt thereof
represented by the general formula (I) exhibits sustained drug efficacy.
[0077] Cytotoxicities noted in neurokinin NK
1 receptor antagonists, neurokinin NK
2 receptor antagonists, and neurokinin NK
1 receptor and neurokinin NK
2 receptor antagonists are reduced in the compound of the present invention or a pharmacologically
acceptable salt thereof represented by the general formula (I).
[0078] When a combined drug of neurokinin NK
1 receptor antagonists, neurokinin NK
2 receptor antagonists (or neurokinin NK
1 receptor and neurokinin NK
2 receptor antagonists), and muscarine M
3 receptor antagonists is used or these antagonists are concomitantly used, distributions
in the lungs need to be examined for the respective ingredients. However, the distributions
are extremely complicated. Distributions in the lungs of a single compound such as
the compound of the present invention or a pharmacologically acceptable salt thereof
represented by the general formula (I) can be easily examined, and drug efficacy can
be confirmed by determining that the compound reaches an affected area.
[0079] The compound of the present invention or a pharmacologically acceptable salt thereof
represented by the general formula (I) is also excellent in terms of high safety.

and deprotection is performed according to a known method (for example, "
Protective Groups in Organic Synthesis" [the method described in Theodora W. Greene,
Peter G. M. Wuts, 1999, Wiley-Interscience Publication]).
[0082] Compounds represented by the general formula (XIII) through the general formula (XXIX)
are known compounds or are produced easily according to a known method or a similar
method using a known compound as a starting material. For example, a compound represented
by the general formula (XIII) is produced according to
U.S. Patent No. 2005/203131.

3 receptor.
(Test Example 7)
[Effect of suppressing methacholine-induced airway contraction (in vivo, intratracheal
administration)]
[0707] A tracheal cannula and a venous cannula were attached to a guinea pig anesthetized
with pentobarbital (50 mg/mL of solution, 0.40 to 0.50 mL/body, subcutaneous administration).
An arterial cannula filled with heparin-containing physiological saline (100 U/mL)
was further attached, and blood pressure and heart rate were monitored via an amplifier
and an instantaneous heart rate meter. Subsequently, gallamine (20 mg/body, intravenous
administration) was administered to terminate spontaneous breathing, and then 10 mL/kg
of positive pressure breathing (Ugo-Basile Biological Research Apparatus, Cat. No.7025)
was rapidly performed at 60 times/min. The airway pressure during artificial breathing
was detected with a pressure transducer (TP-200T or TP-400T; Nihon Kohden Corporation)
attached to a side branch of the tracheal cannula, amplified (AP-601G; Nihon Kohden
Corporation), and recorded in a recorder. After the airway pressure, blood pressure,
and heart rate were stabilized, 30 µg/kg of methacholine was intravenously administered
from the venous cannula to induce airway contraction, and the airway pressure was
measured for the following 10 minutes.
[0708] A test substance was dissolved in 5% glucose solution, and a 0.5 mL/kg solution was
administered intratracheally with an intratracheal administration apparatus (model
1A-1B; Penn-Century, Inc.) 60 minutes before stimulation with methacholine.
[0709] The AUC of increase in the airway pressure over 10 minutes after administration of
methacholine was measured as the intensity of methacholine-induced airway contraction
and calculated as an ID
50 value from the inhibition rate based on the value of the control group (a 5% glucose
solution intratracheal administration group).

and heart rate were stabilized, 20 µg/kg of SP was intravenously administered from
the venous cannula to induce airway contraction, and the airway pressure was measured
for the following 10 minutes.
[0714] The test substance was dissolved in a 5% glucose solution, a 0.5 mL/kg solution was
intratracheally administered with an intratracheal administration apparatus (model
1A-1B; Penn-Century, Inc.) 60 minutes before stimulation with SP.
[0715] The AUC of increase in the airway pressure over 10 minutes after administration of
SP was determined as the intensity of SP-induced airway contraction and calculated
